Correct Thermostat Temp

My rebuilt 318 has a 195* thermostat in it. All my cooling system components are new (Spectra Premium CU526 radiator). Around town driving my AutoMeter Z-Series water temperature gauge shows about 195*ish. On the freeway around 70+ mph it rises to about 205*. These temperatures are with an ambient air of around 85* (it's been hot/muggy here in metro-Detroit).
